Fair enough.  How about we take the transaction id of the final payment and use that to pad the initial hash instead?  This could not be known by anyone until it was too late, negating the ability of the last person to generate a winning address.

Does the dude abide?

Using raw transactions you can know the transaction hash before sending it to the network

In this situation I would alter my program to now generate raw transactions until I find one that the transaction hash would make my address the winner address.

Maybe Smiley  But I have addressed the issue with your concern and posted a fix.  Timestamp is now used to pad the initial hash so you would have to know the exact second the site scripts picked up the final transaction and corresponding address for that second.

I thank you kindly for your help!

But now your algo is not provably fair as no one can verify the timestamp informed by you.

Your provably fair algo is flawed as it doesn't protect the users from being cheated by the last player.

I can create a program to monitor the game address until it has 99 players and then start generating addresses until I find one that will make me the winner.

You are partly right, after some thought.  You are wrong in the fact you cannot generate an address to send from.  Your client, or you, have to spend previous outputs, these cannot be generated by you unless you continually send yourself coins in attempt to generate an output that could win.  This output would have to contain enough coin for the game or it might not be selected as the payment address if multiple previous outputs are used.

So technically yes, this could be achieved through lots of work and many (possibly 100's) of txn fees to the network.

I have come up with a method to account for this and will post an update when the code is in place.

Thanks for taking the time to look at this!

Ok, I'm starting to think you really should spend some time to learn more about Bitcoin.

An address can be generated without the need to send coins to it.

What I will need to do is find the address that will make me the winner and create 2 raw transactions, one sending my coins to the newly generated address and another to send from the newly generated address to you game address.

Re: Win Upto 100BTC!! FREE BITCOIN LOTTERY!!

Actually they have a free lotto and the normal lotto.

In the normal lotto you can win up to 101 btcs betting 0.001. In the free lotto is just like a "faucet lotto" where you can bet to get only 1 btc with 6 numbers.

The odds of getting the 6 numbers out of 67 are 1 in 71,852,901,120 what it is almost impossible to happen. You have 0.016129 (1/67) possibilities to get one number.

1/67 × 1/66 × 1/65 × 1/64 × 1/63 × 1/62 = 1/71852901120



your calcs are wrong.

what you are calculating is the chance to hit all the lotto numbers IN THE ORDER THEY WERE DRAWN.

But that's not how a lottery works, you just need to hit all the number besides the order.

I don't remember now how the odds are calculated but I remember that I have calculated it before and the odds are better than mega millions and power ball.

And another question, how can you prove that you didn't insert a winning ticket after the draw to win the jackpot. Transactions time aren't enough as they did not contain the chosen numbers

Re: Hi Stakes Bitcoin Raffle Lottery |No House Edge|Prog Jackpot|Provably Fair|

If a house ticket is not chosen when draw, 85% (~7.65) goes to winner.


Didn't understood the math. 85% of 10 BTC = 8.5 BTC


There's only one draw per round and only one winner per draw. And the prize is always 85% of jackpot.

Yes, I understood that.


I think you didn't get my point.

ok, now I see that will be house tickets in the initials rounds. So lets do the math again:

You are giving 9 BTC for the first round, so, if I send 1 BTC and I win (66% chance), I will receive 8.5 BTC, if the house win the amount will be available for the next round.

so I will send another 1 BTC for the second round, the total jackpot will be 11 BTC, if I win (76.92% chance) I will receive 11 - 0.5% = 10.945 * 85% = 9.30325 BTC. if the house wins, supposing you will get the house rake from the total jackpot, 10.945 will be available for the next round.

so I will send another 1 BTC for the third round, the total jackpot will be 11.945 BTC, if I win (0.8333%) I will receive 11.945 - 1% = 11.82555 * 85% = 10.0517175 BTC. if the house wins, supposing you will get the house rake from the total jackpot, 11.82555 will be available for the next round.

And on the forth round, as this round will not have house tickets I will have paid a total of 4 BTC and will receive a total of 10.68368315 BTC.

Still easy money.

9 BTC have been promotionally added to the jackpot due to celebration of the first round of the 1st raffle game!

The pot turns the game massive +EV (Positive Expected Value) for players to bet.

Enjoy the bonus!

HuhHuhHuh


Ok, I didn't read all your first post because it is really long. So forgive me if my questions was covered in it.

But this looks like too easy money, as far I could see, there will be 10 tickets of 0.1, so I just need to send 0.1 from 10 different address (1 BTC total) and I will receive 8.5 BTC (after the house rake). Am I right?


Another thing, I couldn't see the point of the house rake. on the first draw the winner will receive 8.5 BTC, on the second draw, the winner will receive 9.775 BTC, on the third draw 9.96625. As you could see, the winnings will tend to 10 BTC.
So, why the need of house rake?

Forgot about one thing.

if I have 0.01% of winning 400x my bet, as far as there are enough coins on the jackpot the players still have a positive Expected Return.


After playing 10000 bets my expected return is 9992 bets plus 400 and this will give me 10392, so my Expected Return is a positive 3.92%.


So, still too shady for me.

I'm sure they apply the 0.8% house edge before the bet... right?  So in the 51/100 bets- which are losers they take 1% for the Jackpot.  And they pay 0.1% to referrals.  Your math is just wrong in regards to a house edge. If I said I had a 1% house edge and gave 95% of losing bets to my Mom... My house edge is 1%.

Well, maybe they are doing this way, putting the "house edge" on the flipping instead on the returned amount (I really doubt they are doing this, we can't call this the "house edge" on this situation, and they really need to explain this on the site). But your math isn't right also, they're not giving the jackpot to their Mom, the jackpot means that amount will be back to the players sooner or later. So this value should be deduced from the "house edge".

So in the situation above we have (in my understanding):

0.8% "house edge" means that in 1000 plays 496 will win and 504 will lose. so 504-496 will give us 8 plays to the house (0.8%)

from all the 504 loses they are putting 5.04 to the jackpot - this leaves the house with 0.296% house edge.

in the best situation there will be 0% players referred in the site and in the worst situation there will be 99%
so this will put house edge about 0.197% and 0.296%. Very low in my opinion.

Besides that we found a positive house edge in the situation above, I still won't play in a site with that low house edge and not provably fair.

This is simply you not reading the rules.  The max jackpot is 400x your bet.

i forgot about that, tks for clarifying, but still doesn't make sense, see below.

I'm missing something here.

The site is to shady for me, I think I need explanations on:

- You are saying that "Each time you win, we double your bet" and also "We have a low house edge of just 0.8%". How can this be possible? if you're doubling our bet everytime we win, in a fair random system your house edge is 0%. But yet you are giving 1% of the losing bets (50%) to the jackpot and also 0.1% to the referred players. This make you house edge -0.6%. I'm really sure you isn't a wealthy person donating your money to the poor players of your site, so, unless you can prove that your site is generating fair random numbers, you are just scamming people on your site.

- You said here: "As for jackpots: the chance to win a jackpot is 0.01%". Wow, so this is a nice form to win easy money from your site. Well, the bitcoin jackpot is at 43 BTC, but the minimum bet size is 0.00001. Statistically if I bet a total of 10000 bets of 0.00001 (total of 0.1 BTC) I have 100% of chance of winning 43 BTC, niiiiiiice. You should be asking why I didn't try to win this jackpot before posting this here. because we have a saying in my country that says: "when the alms is big, the saint distrusts" or using a known english sentence: "it's too good to be true".
